You don't know that... the original article was vague about the position of the actors.You are omitting the key fact: the defendant left the situation, retrieved his gun and re-entered the fight.
Guilty.
Weiss, who has a permit to carry a gun, told the police that after feeling threatened by Rahim’s passenger and returning to his car to get his phone and firearm, he warned the passenger that he was armed.
That piece never said that they had a confrontation at point A and Weiss went to his car and came back to point A. It could be that the dead guy and his friend followed him to the car. And then approached Weiss further when he saw the gun. Who knows? and that will likely go a long way in determining his guilt or innocent.
But many on here are assuming that Weiss went to his car to get the gun and then came back to the spot of the original confrontation... I see nothing to validate that belief.
How far must one "retreat"??
